Abstract
The invention relates to an electrical engineering appliance, in particular to a moisture absorber used for a transformer and a mutual inductor, wherein the moisture absorber comprises a shell; two completely same purification chambers which are connected in parallel are arranged in the shell; a humidity sensor is arranged in each purification chamber; the purification chamber is completely partitioned by adopting a partition plate directly; automatic valves are arranged on the top and the bottom of each purification chamber; and an exhaust hole is also formed on the top of each purification chamber. After the design is adopted, when one purification chamber is maintained, the purification chamber can be switched to the other purification chamber to keep normal operation, so that the normal operation of the moisture absorber cannot be influenced during dehumidification, and more installation space is saved compared with that of the design with two moisture absorbers.
Description
Technical field
The present invention relates to a kind of power engineering apparatus, be specifically related to the dehydrating breather that a kind of transformer and instrument transformer are used.
Background technology
Power transformer generally passes through capsule or wavy metal with transformer oil and air insulated, makes moist to avoid transformer.Impurity such as airborne moisture can have a negative impact to the life-span of capsule or wavy metal, in case capsule or wavy metal are damaged, then transformer oil will make moist, thereby influences transformer life.In order to improve the useful life of capsule or wavy metal, reduce the danger that transformer makes moist, general pneumostome at capsule or wavy metal connects dehydrating breather and removes impurity such as airborne moisture.
Along with the progress of transformer technology, the requirement of intelligent control is strong day by day.Some structures, the annex of tradition dehydrating breather is unfavorable for intelligent control, just progressively eliminates, and transformer technology, annex are to intellectuality non-maintaining aspect development.The tradition dehydrating breather needs manual maintenance to be unfavorable for realizing intelligent.The present domestic weight sensor of taking also has and takes humidity sensor as recognition system; What the dehydrating breather of external some enterprise was taked is humidity sensor, utilizes water vapour to meet the wall cooling from bottom discharge; The dehydrating breather scheme that also has has adopted two dehydrating breathers, can switch to another dehydrating breather work during one of them dehumidifying, reaches reduction annex volume but above-mentioned technology all is difficult to perfection, improves the purpose of intelligent control.
Summary of the invention
Many weak points to prior art exists the invention provides the dehydrating breather that a kind of transformer and instrument transformer are used, and this dehydrating breather comprises housing; Be provided with the identical clean room of two parallel connections in the housing, be provided with humidity sensor in each clean room, and the clean room directly adopts dividing plate to isolate fully; Top, clean room and bottom are provided with automatic valve; The top, clean room also is provided with steam vent, adopt this design after, when a clean room safeguards, can switch to another clean room and keep operate as normal; Do not influence the dehydrating breather operate as normal in the time of can either satisfying dehumidifying, again than using two dehydrating breathers to save installing space.
The concrete technical scheme that the present invention adopted is: a kind of dehydrating breather; Comprise housing, be provided with the identical clean room of two parallel connections in the housing, be provided with humidity sensor in each clean room; And the clean room directly adopts dividing plate to isolate fully; Top, clean room and bottom are provided with automatic valve, and the top, clean room also is provided with steam vent, are provided with heater in the clean room.
After adopting this design, when a clean room safeguards, can switch to another clean room and keep operate as normal, not influence the dehydrating breather operate as normal in the time of can either satisfying dehumidifying, again than using two dehydrating breathers to save installing space.Detailed process is: at first utilize in this clean room of humidity sensor identification in the clean room whether need dehumidifying; If need dehumidifying in this clean room; The automatic valve that then is provided with through top, clean room and bottom; This clean room is closed the steam vent of opening simultaneously in this clean room, can operating state be switched to another clean room; Start the heater heats dehumidifying in this clean room then, and utilize the low rising principle of hot water and steam density from the working chamber top steam vent discharge water steam; Judge whether to dehumidify to finish through humidity sensor at last, dehumidifying finishes and then closes steam vent and automatic valve makes this clean room subsequent use.
The dehydrating breather housing is provided with control cabinet, and the housing bottom is connected with the filter chamber, and the top is connected with ring flange, can make things convenient for being connected of dehydrating breather and other equipment like this.
In sum; After adopting the dehydrating breather of this structure; When a clean room safeguards, can switch to another clean room and keep operate as normal, not influence the dehydrating breather operate as normal in the time of can either satisfying dehumidifying, again than using two dehydrating breathers to save installing space; Realize Based Intelligent Control, be the full intellectualized advantage that provides of whole transformer or instrument transformer.
